This Week in Elasticsearch and Apache Lucene - 2017-03-27

Welcome to
This Week in Elasticsearch and Apache Lucene! With this weekly series, we're bringing you an update on all things Elasticsearch and Apache Lucene at Elastic, including the latest on commits, releases and other learning resources.

Apache Lucene

Lucene 6.5.0 is going out soon

The vote for the release candidate has passed. In particular, this release will bring faster range and geo queries to Elasticsearch, as well as improvements to the way query parsers deal with token graphs, see below. You can read more about the release highlights at https://wiki.apache.org/lucene-java/ReleaseNote65.

The Findbugs static analysis tool findswarnings that maybe we should fix.

The ascii folding token filter is slow due to a too large method. There is a simple hack that can fix it but we would like to apply a proper fix by storing the replacements in a data-structure rather than a giant switch/case block.
